ElevenLabs STT

Overview

ElevenLabs speech-to-text is available in LiveKit Agents through LiveKit Inference and the ElevenLabs plugin. Pricing for LiveKit Inference is available on the pricing page.

LiveKit Inference

Use LiveKit Inference to access ElevenLabs STT without a separate ElevenLabs API key.

Usage

To use ElevenLabs, use the STT class from the inference module:

from livekit.agents import AgentSession, inference

session = AgentSession(
    stt=inference.STT(
        model="elevenlabs/scribe_v2_realtime", 
        language="en"
    ),
    # ... tts, stt, vad, turn_detection, etc.
)

Parameters

Multilingual transcription

ElevenLabs Scribe 2 Realtime supports multilingual transcription for over 90 languages with automatic language detection.

String descriptors

As a shortcut, you can also pass a model descriptor string directly to the stt argument in your AgentSession:

from livekit.agents import AgentSession

session = AgentSession(
    stt="elevenlabs/scribe_v2_realtime:en",
    # ... tts, stt, vad, turn_detection, etc.
)

import { AgentSession } from '@livekit/agents';

session = new AgentSession({
    stt: "elevenlabs/scribe_v2_realtime:en",
    // ... tts, stt, vad, turn_detection, etc.
});

Plugin

Use the ElevenLabs plugin to connect directly to ElevenLabs' STT API with your own API key.

Installation

Install the plugin from PyPI:

uv add "livekit-agents[elevenlabs]~=1.4"

Authentication

The ElevenLabs plugin requires an ElevenLabs API key.

Set ELEVEN_API_KEY in your .env file.

Usage

Use ElevenLabs STT in an AgentSession or as a standalone transcription service. For example, you can use this STT in the Voice AI quickstart.

from livekit.plugins import elevenlabs

session = AgentSession(
   stt=elevenlabs.STT(
      model="scribe_v2_realtime",
   ),
   # ... llm, tts, etc.
)
